It is unconstitutional for a state to force a teacher to teach religion in a science class. The Discovery Institute, which has been spearheading this effort, knows that this case is a loser and has refused to support the ID side.
If you want to know why DI backed out it is simple. They ar smart enough to know that intelligent design has to come up with some actual science befor it can be taught in a science classroom.
There's a lot of name calling going on, but the
Discovery Institute knows that ID hasn't produced any science yet. If and when it does, it will be taught.
If you have children in public school, you know ID/creationism is being taught along side evolution in many areas and many, many people don't seem to mind. Sad for you, isn't it?
